Control Manifolds and Valves

Functions of manifolds and valves in hydraulic systems

With the right manifolds and valves, a hydraulic circuit can be controlled and protected precisely:

• Directional control valves: switch the flow between pump, tank and actuators and define movement direction.
• Pressure relief and safety valves: protect the system from excessive pressure.
• Check and counterbalance valves: prevent unwanted backflow and uncontrolled load movements.
• Throttle and flow-control valves: adjust speed and allow fine control of movements.
• Manifolds and modular blocks: combine multiple functions in a compact assembly.

Typical applications

Control manifolds and valves are used in virtually all hydraulic fields:

• lifting systems, workshop presses and clamping fixtures
• mobile hydraulics on construction machines, vehicles and cranes
• industrial machinery, test rigs and special-purpose equipment
• multi-cylinder systems with several tools or actuators

Selecting the right manifolds and valves

When specifying manifolds and valves, consider:

• maximum working pressure and required safety margin
• flow rate and port sizes (threaded, flanged or cartridge type)
• required valve functions (e.g. 3/2, 4/3 directional, mono- or bistable)
• necessary safety functions such as pressure limitation and load holding
• installation environment – stationary plant, mobile machine, outdoor use
